Measuring the speed of light with electronics


https://www.electronics-lab.com/measuring-speed-light-electronics/

The speed of light in vacuum is a well-known universal constant and is considered to be the nature’s ultimate speed limit. No matter, energy, and information can travel faster than this speed. The speed of light has always been a topic of great interest and significance throughout history. In the course of measuring the speed […]

Inductive Proximity Switch Using TCA505


https://www.electronics-lab.com/inductive-proximity-switch-using-tca505/

This circuit is used to design an inductive proximity switch. The resonant circuit of the LC oscillator is implemented with an open half-pot ferrite and capacitance in parallel (pin LC) and if a metallic target is moved close to the open side of half pot ferrite, energy is drawn from resonant circuit and the amplitude […]

LTC3623 – Switching regulator doubles as Class-D audio amplifier


https://www.electronics-lab.com/ltc3623-switching-regulator-doubles-class-d-audio-amplifier/

Clemens Valens @ elektormagazine.com discuss about LTC3623 switching regulator which can be used as Class-D Audio Amplifier. Sure thing, Elektor has published several designs of adjustable power supplies based on switching regulators, so we know that doing this properly in a reproducible way and without making things overly complex requires some serious head scratching. The […]

Raj @ embedded-lab.com has revised his RGB Matrix Display Shield to an improved version. The shield now also carries the DS1307 RTC chip on board along with a CR1220 coin cell battery holder on the back. It is applicable for driving popular 16×32 RGB matrix panels with HUB75 (8×2 IDC) connectors. Row and column driver circuits are […]

Test application for the FPGA Tibbit in the smart LED controller configuration


https://www.electronics-lab.com/test-application-fpga-tibbit-smart-led-controller-configuration/

This application example shows how to connect and use RGBW LED stripe with TPS hardware platform. The main difficulty is that LEDs have their own color generation circuit inside. New FPGA Tibbit #57 can generate fast PWM signal, which is needed for proper LEDs operation. Also, the topic shows the main advantage of FPGA technology. […]

Arduino Wiring, A New Choice for Developers On Windows 10 IoT Core


https://www.electronics-lab.com/arduino-wiring-new-choice-developers-windows-10-iot-core/

Last year, Arduino and Microsoft announced a strong partnership and Windows 10 became the world’s first Arduino certified operating system. This partnership made the creation and innovation much easier with the hardware capability of Arduino and the software capabilities of Windows. Early this month, Arduino Wiring became a new programming language for Windows 10 IoT […]

Arduino radar using sound waves


https://www.electronics-lab.com/arduino-radar-using-sound-waves/

A radar system uses high frequency radio waves for object detection. A high-power RF pulse is transmitted into space and its echo reflected off from an obstacle is recorded. By computing the time elapsed between the transmitted and reflected pulses, and knowing that the electromagnetic wave propagates at a constant speed of light, the radar […]

Using VL53L0X With Arduino to Measure Height


https://www.electronics-lab.com/using-vl53l0x-arduino-measure-height/

Usually, when measuring a child’s height at home, a mark is drawn on the wall then the height is measured using a measuring tape. This process is not always easy and it may has low resolution. In an attempt to simplify this procedure, a new project was developed using an Arduino and a distance sensor. […]
